Whenl these baske s have been placed in position and filled, e third type. of basket 14 is employed 'to lform the I loors.l Each of lthese baskets has an open-ended body porL tion 23 substantially similar to they baskets 10 and the bodyq portion 21 of the baskets 13, but extendingoutwardfrom the. basket andin alinelnent with the bottom thereof,

there is provided 'anextension' 24 of a width equal to the length of' the basket, and ol? a length substantially equalto the lengthof the girders.

is bordered byireinforcing bars '25 integral These baskets are placed in position with the body portion termini,Y apart of the Wall and the extensions 124i4 leadingr across thefspaee betweenV the .Wall and an adjacent` girdery parallel thereto. The body portion ofthcse baskets is then iilled with concrete to unite with the concrete of the baskets below, and

:t thin layer .ofconcrete is spread upon vthe extensions 24, to form the tloor ofthe bui-ld.- ing. Above the body portions of the baskets 14 and l2 are then placed/other, series of.

baskets l() and 11 and the Walls and columns arefeontinued.upward 'to .the next floor, at which point the 'baskets of the type abovedescribed. are inserted tol'orm a1sccond series ol igirders and a second lloor. 'lo conceal tlje wire mesh forming the Walls ol' the several baskets, the sides'of each eolumn and thefacefof the Walls arepreferably provided with afmeting 26 of `cement mortar vwhich lirrnly adheres to the rougi surface ol the baskets.. v Having thus described 'rny invention, I claim as new and desire to secure by l .etters latentz- 1.
